Echinacea plant named ‘Catharina’

ABSTRACT

A new and distinct  Echinacea purpurea  cultivar named ‘CATHARINA’ is disclosed, characterized by distinctive double dark pink flowers and uniquely strong peduncles. The new cultivar also have unique ray florets that resist drooping after harvest. The new variety is an  Echinacea , and is normally used as a garden or container plant, and also suitable for cut flower production.

Latin name of the genus and species: Echinacea purpurea.

Variety denomination: ‘CATHARINA’.

BACKGROUND OF THE INVENTION

The new cultivar was discovered as a chance, whole plant mutation in a commercial nursery in Rijpwetering, the Netherlands. The inventor, Cornelis Petrus van der Meer, a citizen the Netherlands, discovered the new variety as a naturally occurring whole plant mutation among several plants of the unpatented commercial variety, Echinacea purpurea ‘Magnus’. The new variety was discovered in Spring of 2006 by the inventor.

Asexual reproduction of the new cultivar ‘CATHARINA’ by vegetative divisions was performed at a commercial nursery in Rijpwetering, the Netherlands in the Summer of 2006. Subsequently, reproduction has also been successful by tissue culture. Vegetative reproduction by tissue culture has produced several generations, and has shown that the unique features of this cultivar are stable and reproduced true to type through successive generations.

SUMMARY OF THE INVENTION

The cultivar ‘CATHARINA’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘CATHARINA.’ These characteristics in combination distinguish ‘CATHARINA’ as a new and distinct Echinacea purpurea cultivar:

-   -   1. Distinctive double dark pink flowers.     -   2. Uniquely strong peduncles.     -   3. Suitability for garden uses, and commercial cut flower         production.     -   4. Durability of ray florets to resist drooping after harvest.

PARENT COMPARISON

Plants of the new cultivar ‘Catharina’ are similar to plants of the parent variety Echinacea purpurea ‘Magnus’ in most horticultural characteristics. However, plants of the new cultivar ‘CATHARINA’ produce double flowers, or a different color of pink. Additionally, ray florets of ‘Magnus’ will droop within a few days of harvesting flowers for cut flower purposes. Cut flowers of ‘Catharina’ will resist drooping ray florets for a minimum of 7 days.

COMMERCIAL COMPARISON

In addition to the parent variety, ‘Catharina’ can also be compared to the patented, commercially known variety Echinacea purpurea ‘Pink Double Delight,’ U.S. Plant Pat. No. 18,803. The new variety produces overall darker pink flowers, on a shorter plant. Additionally the ray florets of the new cultivar have a different shape, droop less and remain intact longer after harvesting a cut flower.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph in FIG. 1 illustrates in full color a typical plant and flowers of ‘CATHARINA’ grown outdoors in Abbennes, the Netherlands. The plant has been growing in the ground for approximately 2 years. The photograph was taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.
